“…CP was collected from bench‐scale juice processor after extraction of juice from citrus fruits. While collecting CP, only pulp waste was collected without outer covering peel of citrus fruit as it contains high limonene, which is inhibitory to anaerobic microbes . Fresh CM was collected from a livestock farm located in Madikonda, Kazipet.…”

Anaerobic digestion of organic waste is a promising alternative to landfilling and is being encouraged by current policies in India. However, nutritional imbalance of single waste as a substrate in anaerobic digestion is limiting the effective degradation in biogas production. Co‐digestion of multiple organic wastes where the digestion of two or more substrates is carried out in a single digester is a promising method to enhance the nutritional balance. The present study investigated the possibilities of improving biogas production with co‐digestion of citrus pulp (CP), lawn grass (LG), and chicken manure (CM) based on the total solid loading (TS %). The design of experiments and analysis of the co‐digestion effect were carried out with central composite design (CCD) and response surface methodology (RSM), respectively. Biogas production was found to vary more with respect to total solid loading (TS %) than C/N ratio of the co‐digestion mix. The low influence of C/N ratio may be due to prevalence of optimal C/N ratio of 16–33 in all co‐digestion mixes. The adopted central composite design–response surface methodology (CCD–RSM) led to maximum biogas production of 688 mL at CP of 0.28 (TS %), LG of 9.4 (TS %), and CM of 4 (TS %). The CCD–RSM is a suitable approach to maximize the biogas production in multi‐substrate anaerobic co‐digestion. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019

“…These three volatile compounds are known as an antimicrobial agent. The previous experiments demonstrated that methane production was interrupted due to the presence of limonene with half maximum inhibitory concentration, IC 50 was 669 mg/kg [20]. Phloretin in Apple was also reported to cause growth inhibition of some Gram positive and Gram-negative bacteria such as Staphylococcus aureus and Salmonella typhimurium, respectively with a MICs 125 μg/mL [21].…”

This research was aimed to optimize hydrogen production from fruit waste, particularly on the effect of the substrate-toinoculum ratio (SIR). Production of hydrogen was carried out through dark fermentation process both in mesophilic (30 °C, 1 atm) and thermophilic (55 °C, 1 atm) condition. Fermentation was conducted at SIR value ranging from 0.800 to 174 VS substrate /g VS inoc. In mesophilic fermentation, the highest cumulative total gas yield was achieved at SIR value of 19 corresponding total gas yield of 113 ml STP/g VS (5%v of H 2). In thermophilic condition, the highest H 2 yield was obtained at SIR value of 0.800 VS substrate /g VS inoc with H 2 yield of 294 mL STP/g VS (50-60%v of purity). It was noticed that the lower SIR value, the higher hydrogen yield. In summary, it is concluded that substrate-to-inoculum ratio (SIR) plays important role in dark fermentation process to produce renewable energy of hydrogen fuel.

“…Así mismo Sharma, Mahato, Hwan Cho & Rok Lee (2017), indican que las industrias procesadoras de cítricos presentan grandes cantidades de desechos de cáscara de naranja al año, lo cual constituyen un 50% de masa de fruta húmeda. La naranja presenta características muy particulares, como lo son un alto contenido de humedad y carga orgánica, bajo pH, baja biodegradación y la presencia de aceites esenciales que inhiben el proceso de compostaje y fomentan condiciones anaerobias (Ruiz & Flotats, 2016).…”

Revisión de alternativas sostenibles para el aprovechamiento del orujo de naranja Los residuos de naranja se producen en grandes cantidades a nivel mundial por lo que si sus desechos no son manejados adecuadamente pueden generar contaminación en el agua, suelo y aire, afectando los recursos naturales. La técnica del compostaje de residuos de naranja es un factor condicionante en el proceso de degradación por sus características fisicoquímicas y microbiológicas entre las que se encuentran el alto contenido de humedad, acidez, baja descomposición y la presencia de aceites esenciales que retardan el proceso de compost. De acuerdo a la revisión bibliográfica, se analizaron diversos tratamientos para la transformación de los residuos de naranja en el compostaje; se encontró un registro de investigaciones desarrolladas con métodos tales como; aireación forzada o por volteo manual, al aire libre, con adición de hidróxido de calcio, con residuos agroindustriales, con residuos de poda, con residuos de origen urbano, con estiércol de vaca y otro tipo de técnicas diferentes como la producción de biocombustibles y/o la extracción de aceites esenciales. El estudio demostró que es posible disminuir el impacto ambiental en los residuos de naranja para la técnica de compostaje mediante un pretratamiento de deshidratado o la extracción de la pectina y D-limoneno, con el fin de optimizar el tiempo de descomposición; así como mejorar las condiciones físico químicas y microbiológicas del compost. Es importante resaltar que otra opción para el aprovechamiento de cítricos encontrada es la reconversión del desecho a procesamiento industrial, biogás o bioetanol para la obtención de nuevos productos.
